A plurality of barricade arrays 16 are formed on the substrate 14, each barricade array 16 can have a plurality of barricades 20 to be used for accommodating organic luminous printing ink, wherein an orientation D of a plurality of barricades 20 of each barricade array 16 also similarly with the border 15 folder tilt angle theta as shown in Figure 1 of substrate 14.A plurality of organic light emission pixels 18 move with respect to substrate 14 and utilize nozzle 13 sprays of ink gun 12 to drip the organic light emission printing ink along the direction M that advances perpendicular to one of border 15 with each ink gun 12 and are formed on the substrate 14 to the modes in its corresponding barricade 18, provide image display function with the image display area on the common formation organic electroluminescence display panel 10, in this embodiment, a plurality of organic light emission pixels 18 can be elongated or circular Organic Light Emitting Diode (Organic Emitting Light Diode, OLED) and preferably be mosaic (Mosaic) arrangement or striated (Stripe) and arrange (but not as limit), for instance, be among the embodiment of mosaic arrangement in employing, the organic light emission pixel 18 that is positioned at same barricade array 16 can be elongated and be put in order to be formed on the substrate 14 and adjacent organic light emission pixel 18 has different glow colors according to RGB (RGB).
In addition, as shown in Figure 1, organic electroluminescence display panel 10 can comprise in addition a plurality of data and write lambda line (data line) 22 and a plurality of scan line (scan line) 24, each data is write lambda line 22 and each scan line 24 and is respectively coupled to corresponding organic light emission pixel 18 with the light emitting control that is used for carrying out each organic light emission pixel 18 and so that organic electroluminescence display panel 10 can show corresponding image, wherein data are write the circuit trace of lambda line 22 and each scan line 24 and are controlled the related description that designs and are common in the prior art, repeat no more in this.
Below be described in detail for the manufacturing process of the organic light emission pixel 18 on the organic electroluminescence display panel 10, please consult simultaneously Fig. 1 and Fig. 2, Fig. 2 is the flow chart of the method for the manufacturing organic electroluminescence display panel 10 that proposes according to one embodiment of the invention, and it can comprise the following step.
Step 200: on substrate 14, form a plurality of barricade arrays 16;
Step 202: the direct of travel M perpendicular to the border 15 of substrate 14 moves with respect to substrate 14 with each ink gun 12 edge;
Step 204: at least one of them nozzle 13 spray with a plurality of nozzles 13 are dripped organic light emission printing ink and are formed at least one organic light emission pixel 18 at least one barricade 20.
Be simplified illustration, only describe for as shown in Figure 1 single ink gun 12 forms corresponding organic light emission pixel 18 on substrate 14 steps flow chart in this, as for the related description that forms the steps flow chart of organic light emitting pixel 18 for other ink guns 12, it can be by that analogy, therefore repeat no more.At first, need to form at substrate 14 and be used for a plurality of barricade array 16(steps 200 of accommodating organic luminous printing ink), as shown in Figure 1, each barricade array 16 can have the border 15 folder tilt angle theta of orientation D and the substrate 14 of a plurality of barricades 20 and a plurality of barricade 20, each barricade 20 can adopt and generally common are machine light emitting pixel barricade technique (such as photoetching process etc.) defining the forming area of corresponding organic light emission pixel 18 at substrate 14, occurs thereby avoid organic light emission printing ink because of different color mutually to mix the colour mixture problem that causes.
After the moulding of finishing a plurality of barricade arrays 16, it can ink gun 12 moves (step 202) along the direct of travel M perpendicular to the border 15 of substrate 14 with respect to substrate 14, wherein as shown in Figure 1, the orientation D of ink gun 12 and each barricade array 16 can press from both sides tilt angle theta with border 15 respectively, in more detail, in actual applications, tilt angle theta can meet following formula.
Tilt angle theta=cos
-1(spacing d of adjacent barricade array 16
1One spacing d of the adjacent nozzle 13 on/each ink gun 12
2).
Thus, the design that all has identical tilt angle theta and move with respect to substrate 14 along the direct of travel M perpendicular to the border 15 of substrate 14 with ink gun 12 with respect to the border 15 of substrate 14 by above-mentioned ink gun 12 and each barricade array 16, the present invention can reach all identical purposes of nozzle quantity that each ink gun 12 can use when organic light emission printing ink is dripped in each spray, for instance, as shown in Figure 1, in spray the process of dripping organic light emission printing ink along direct of travel M, ink gun 12 is at the two dotted line l perpendicular to border 15 that are positioned at as shown in Figure 1
1, l
2Between the quantity of the nozzle 13 that can use all identical.
At last, in step 204, ink gun 12 can utilize nozzle 13 spray when ink gun 12 is aimed at barricade 20 of equal number to drip organic light emission printing ink to barricade 20, by this, as shown in Figure 1, ink gun 12 can form respectively corresponding organic light emission pixel 18 barricade 20 is interior, and as for the moulding of other organic light emission pixels 18, it can be by that analogy.Thus, each organic light emission pixel 18 as shown in Figure 1 can be all identical and cause each printing ink spray of nozzle to be dripped in the consistent situation of capacity in the quantity of the nozzle 13 that ink gun 12 can use when organic light emission printing ink is dripped in each spray, be formed in order on the substrate 14, so as to effectively solve mention in the above-mentioned prior art because of ink gun when each spray oil dripping China ink employed nozzle quantity all each printing ink spray of the not identical nozzle that causes drip the inconsistent problem of capacity, thereby make organic light emission pixel 18 can have good moulding quality, to promote the performance of organic electroluminescence display panel 10 on image color shows.
Should be noted; the above-mentioned design about organic light emission pixel 18 of mentioning (being the arrangement mode of organic light emission pixel 18 and shape etc.) and on substrate 14 quantity of formed barricade 20; the quantity of the nozzle 13 that ink gun 12 uses with its quantity of organic light emission pixel 18 of corresponding formation all can not be subject to Fig. 1; it can change to some extent according to the practical application request of organic electroluminescence display panel 10; in other words; so long as utilize ink gun and each barricade array all to have the design that is configured to carry out organic light emission pixel moulding process at identical angle of inclination with respect to the border of substrate, all belong to protection scope of the present invention.
Compared to prior art, the present invention is used for folder angle of inclination, border and the design parallel with pixel with need of each ink gun of orientation and substrate of barricade of accommodating organic luminous printing ink, to reach all identical purposes of nozzle quantity that each ink gun can use when organic light emission printing ink is dripped in each spray, so as to producing each printing ink spray consistent effect of capacity of nozzle.Thus, by above-mentioned design, the present invention can guarantee that the organic light emission pixel can have good moulding quality, and then promotes the performance of organic electroluminescence display panel on image color shows.
The above only is preferred embodiment of the present invention, and all equalizations of doing according to claim scope of the present invention change and modify, and all should belong to covering scope of the present invention.
